optics|ˈɒptɪks|
[A pl. of optic a., used subst. to render med.L. optica pl. neut., a. Gr. τὰ ὀπτικά, optical matters, optics (Aristotle, Ptolemy, etc.): see -ics. Besides this, Greek had also ἡ ὀπτική (sc. θεωρία) the theory of the laws of sight, whence L. opticē in Vitruvius.
The med.L. optica occurs c 1160 in the Sicilians, Henricus Aristippus who speaks of Euclidis Optica, and Eugenius who translated from Arabic the Ὀπτικά of Ptolemy under the title Optica Ptolomæi. Optica appears later as a fem. sing., and still in 16th c.; thence OIt., Sp., Pg. optica, It. ottica, F. l'optique sing. fem., also Eng. optic n. sing. In the 16th c. was also used L. opticē after Gr.]
The science of sight, or of the medium of sight, i.e. light; that branch of physics which deals with the properties and phenomena of light. Plural in origin and form, and formerly so construed (‘the Optics’); but now always as singular; less usually made singular in form (like F. l'optique, OIt., Sp., Pg. optica): see optic n. 4.
